Candle Helper - Candle Mushrooming: What It Is and How to Prevent It

Candles have been used for centuries as a way to provide light, warmth, and ambiance. They come in a wide variety of shapes, sizes, and scents, making them a versatile decoration for any home. However, one aspect of candle burning that can sometimes cause confusion is mushrooming.

Mushrooming is a phenomenon that occurs when the wick of a candle burns too hot, causing a build-up of carbon on the wick that creates a small, mushroom-shaped protrusion. While some people might find mushrooming aesthetically pleasing, it can be a sign of an issue with the candle's burning conditions.

One of the main causes of mushrooming is a wick that is too large for the candle's diameter. When the wick is too big, it will burn too hot and cause the carbon build-up that leads to mushrooming. To prevent this, it's important to choose a candle with a wick that is appropriately sized for its container.

Another factor that can contribute to mushrooming is burning the candle for too long. If a candle burns for too many hours at a time, it can cause the wax to heat up too much, leading to the formation of the mushroom shape. To avoid this, it's recommended to burn candles for no more than 4 hours at a time and to trim the wick before each use.

Additionally, the type of wax used in the candle can also affect mushrooming. Soy wax and beeswax are less likely to produce mushrooms compared to paraffin wax, which is more commonly used in mass-produced candles.

It's worth noting that while mushrooming can be unsightly, it typically doesn't affect the burn quality or safety of the candle. However, if you notice excessive mushrooming or other signs of a poorly burning candle, such as a large flame or black soot on the container, it's best to extinguish the candle and discontinue use.

In conclusion, mushrooming is a common but easily preventable issue that can arise when burning candles. By choosing the right size wick, burning candles for shorter periods, and selecting candles made from certain types of wax, you can reduce the likelihood of mushrooming and enjoy a safer and more pleasant candle-burning experience.
